摘要
分别用 Gruber、Lange法和大角外推法处理了反式聚异戊二烯溶液的光散射数据,并将所得结果与渗透压、粘度和GPC法的分析结果进行了分析、比较。结果表明,用Gruber法得到的各试样溶胶的重均分子量和微凝胶的含量比较合理。
The. solution properties of microgel - containing trans - polyisoprene solution were studied with light scattering. For the evaluation of light scattering data, the procedures suggested by Gruber and Lange, as well as the method of extrapolation of the values measured at large angles to zero angle were used. The results were compared with those obtained by osmotic pressure, viscosity and GPC methods. The results showed that the weight average molecular weight and the weight fraction of microgel, both obtain...
